China is insisting on the withdrawal of Indian troops from the Doklam area as a pre-condition for holding dialogue on resolving the border problem.

"The Indian government has repeatedly recognised the effectiveness of the 1890 Convention on the boundary between Tibet and Sikkim".

China and India have been engaged in the standoff in the Doklam area near the Bhutan tri-junction for the past three weeks after a Chinese Army's construction party attempted to build a road.

The Indian media reports claims that despite the government's position that a meeting between the two sides was never planned, China conclusively ruling it out was being seen as a hardening of its stance.

Geng said the convention between Great Britain and China relating to Sikkim in 1890 stated that the Sikkim section of the boundary commences from the east of Mount Gipmochi.

As India prepares for a naval exercise in the Indian Ocean with Japan and the United States on July 10, China on Friday expressed "hope" that the naval drill was not aimed at "any third party", even as troops from both countries remained locked in a standoff in Sikkim. "That is absurd and out of ulterior motives", Geng added.

In 2014, hundreds of Indian and Chinese troops faced off on the de facto border known as the Line of Actual Control that runs along the northwest Indian region of Ladakh, overshadowing a visit by China's president Xi Jinping. However, China claims that it is a part of its Donglang region. "India should immediately break all trade ties with China", said Vipin Manothiya, Meerut Mahanagar president of SP's SC-ST Cell."Just like China encroached upon areasin Sikkim, it is trying to encroach in Doklam".

India has said Beijing's action to "unilaterally determine tri-junction points" violated a 2012 India-China pact which says the boundary would be decided by consulting all the concerned parties.

It said the stand-off has also "impaired the independence of Bhutan, one of the world's smallest countries, which is closely allied with India".

"The Indian side introduced the idea of tri-junction point into the incident and attempts to enlarge the point into an area".
